To all whom it may concern:

Be it known that 1, JOHN H. Fox, a citizen of the United States, residing at 228 East One-hundred and Twenty-third street, New

York, county of New York, and State of New'York, have invented certainnew and useful Improvements in Injector-Carbonators, fully described and represented in the following specification and the accompanying drawings, forming a part of the same. i The present invention relates to 'anapparatus for effecting the continuous carbonation of water as it is drawn from a fountain for use. as a beverage, the apparatus being supplied automatically with gas and water when the carbonated liquid is drawn from its receptacle, and such supply ceasing when the draft from the receptacle stops. The apparatus comprises means fortwice mingling the gas and water together by separate instrumentalities so as to effectually carbonate the water, and it also provides means for mingling free gas with the water as it passes out of the receptacle, to give it a specialsparkling character. The gas is first mingled with the water by an injector, which is made of special construction embracing a checkvalve, to enable it to'supply the carbonator automatically and to prevent the entrance of water to the gas-su ply pipe when the draft from the receptacle ceases. The gasand water are mingled a second time by means of a receptacle containing perforated pans, below which pans the gas and water mingled by the injector are delivered, and the draft from the receptacle is so arranged that the mingled gas and water rise'through the perforations in the pans when there is any draft from the rece tacle. Such movement of the liquid throng 1 the perforations in the pans re eatedly sub-divides the water and re-ming es the same with the gas which has not been absorbed by the water during its mingling in the injector. A portion of such unabsorbed gas necessarily rises in the top of the receptacle, and the water is drawn from if y the receptacle by a tube extended through the bottom and upwardly through the pans into the gas-space above the liquid-in the receptacle where a perforation of the tube in such gas-space permits the free gas to enter the tube whenever li uid is drawn oif, and thus to .mingle'direct y with the water to give the same a sparkling quality.

y "In this invention, each etc in the treat- 'ment of the water is essentia to produce a and a small gas-reservoir or chamber between such check-valve and the gas-outlet, which chamber may contain suiiicient gas to carbonate the water, as one or two glasses,

which would be drawn fromthe receptacle at a single time. The invention also includes a struction for the pans. The invention will be understood by refer- IIGW C011 ence tosthe annexed drawing, in which Figure 1 is a diagram showing thecarbonator and its connections; Fig. 2 is a vertical section of the carbonator; Fig. 3 is a longitudinal section of the injector provided with the check-valve; and Fig. 4 an alterna tive construction for the injectormade of a I single Y-fitting. Figs. 5 to 7 are details of the perforated pans.

In Fig. 1, A designates the receptacle for' 'carbonating water, Bthe injector,f the pipe supplying water thereto, D the pipe supplying gas thereto, and provided with cock E, and F is the pressure-regulator interposed between the injector.

From whatever source the water-supply be drawn the pressure of the gas is regulated, as by the hand-wheel F upon the regulator, a few pounds below that of the water, so that the gas may not'crowd past the water into per' the-receptacle and accumulate in the u part of the same. With such relation 0 the two pressures, the water draws a sufficient quantity of gas through the injector to supply the carbonating rcce tacle with the required mixture of gas an water. i

The receptacle A is shown provided with a series of perforated so-called pans hand with an inlet-pipe g which receives the mixture of gas and water from the injector and discharges it into the bottomof. the receptacle by aperforated pipe 2'. The outlet pi e for' carbonated water is shown connecte at the bottom of the receptacle with a perforated stand-pipe k, theupper perforations Jr serving to draw off any gas t at may accumulate in thetop of the receptacle and thus permit the continuedinfiow of water, which would gas cylinder or tank G and the ioo be obstructed by the accumulationof gas.

Any injector may be usedwhich is provided with two iozzles related to one another in a suitable manner so that the water nozzle may form a partial vacuum in the gas nozzle and draw the gas therefrom so as to mingle the gas and water and discharge the mixture into the receptacle, Fig. 4 showing a YfiX-. ture with a branch 0. for the gas, a'branch f for the water, and abranch g"-for d1scharging the mixture. The water with such an in jector is introduced at a few pounds pressure above that of the gas and operates to draw the gas into the pipe 9 and mingle it with the water in its passage to the carbonating receptacle. The water thus operates because its momentum when discharged from the pipe j" into the pipe g causes a artial vacuum in the pipe 11/ and draws the gas therefrom.

A special construction for. an injector, adapted particularly to maintain the supply of gas to the water, -is shown in Fig.3, in which the injector is formed of a threaded pipe 0 and. suitable fittings. The gas-inlet d is screwed upon one end of such pipe and a valveseat a Is screwed upon the same end, and a check-valve b seated inside of the same and held normally upon the seat by a spring I).

Upon the opposite end of the pipe a teefixture d is screwed with a branch f at one side forthe water supply. A gas-outlet having projectin nozzle (1 is screwed within the same end of the pipe and the nozzle projected forward beyond the tee-fixture d. A tapering discharge-tube g is screwed upon the end of the tee-fixture and contracted to fit rather close to the gas nozzle. The interior of the tee-fixture forms a water-chambere, suplie'd at its side; and discharging the water into the tapering tube past the gas-nozzle so as to draw the gas therefrom. The interior of the pipe 0 forms a small gas-chamber c which is proportioned to contain enough gas to carbonate the contents of the rece tacle A, or such part of the same as wou d be drawn oil at one time. Such a gas-chamher is necessa y where-the pressure of the gas is lower than that of the water, as the gas is unable to flow in to the injector after a period of quiescence until a suflicient flow of water is established to produce a partial vacuum in the chamber a and thus draw a fresh volume of into the gas-nozzle. This construction of the injector renders the operation of the injector and carbonator entirely automatic, when the pressure of the water and the gas su plies are regulated as described. The (rawing off of carbonated water from the pipe is and outlet permits the inflow of water from the injector, which delivers a suitable proportion of gas mingled with it, which, entering the bottom of the receptacle, passes upwardly through the pans h.

from the draft-tube together.

not absorbed by the water necessarily rises I into the top'of the receptacle.

When the apparatus is in continuous oper ation, it is not essential that the gas should all be dissolved in the water, as the gas which is not dissolved is finely diffused through the water and is drawn off by the perforations is, because the opening of the draft-arm almost wholly destroys. the pressure within the pi e k'and causes an instantaneous flow of flui whether it be gas or water, into all the perforations of the pipe. The particles ofjgas in the water space tend to rise, but the re notion of pressure within the ipe It causes them to fiow in the water to the perforations,.and such reduction of pressure also causes the gas to enter the perforations in the gas space, and to pass out of the pipe with the water which is entering the same, the two becomin intimately mingled as they move throng the pipe, so as to flow Such -entrainment of the gas is due to the fact that it is a lighter and more mbbile fluid than water, and when the reduction of pressure occurs within the pipes 7c, the gas entersmore within the pipe toward its inlet. The outflow of the gas fromrtheprevents the accumulation ofgas 1n the upper part of the rece tacle, which; exce t for the as 'space wholly freely than the water and flows more freely perforations in t e gas space, woul accumuate steadily within the receptacle until no room was left for water. avoids the necessity for a vent cock upon the top of the receptacle which has heretofore been commonlyused in such carbonators, throu h which gas must be blown ofi frequent y to discharge the accumulation which prevents the entrance of water. The water drawn from this carbonator has an especially sparkling qfuality due to the entrainment of gas with t tions in the gas and water space.

The check-valve operates whenthe water first moves into the injector, after a draft of carbonated water from the receptacle, to prevent the water from crowding into the gas nozzle d, and backwardly into the gasfrom the tube 9 was established, y reason of the excess of the water pressure above the 'Ilhe) construction- 1e water, by the use of perforagas pressure. The check-valve forces all of" the contents ofthe gas-chamber meanwhile supplying the gas until the movement of the water current produces a suction upon the gas nozzle (1 and allows the gasto enter from the pipe D.

To economize the block-tin or pure sheet tin in the manufacture of perforated pans h, I have devised the special method of manufacture shown in Fi 's. 5, 6 and 7-. Fig.

5 is a plan of a square b ank with a dotted circle representin the size of the is an edge view 0 the pan finishe 7 shows the under side of the pan.

By my new method of manufacture, I cut square sections or blanks h from a sheet of the block-tin, only a little wider than the diameter of the desired pan, and stam the same in dies to bend the four corners own ward to form feet or flanges h which support the pans upon one another as shown in Fig. 1. The points of the corners may be turned inward as shown at 72* in Figs. 6 and 7, to rest an Fi 6 d and upon the top of the pan beneath; but such'a bending inward is not essential. Much less sheetmietal is required to' make each pan by thus utilizing the corners as sup orts or flanges, than where a circular blan: is employed of sufficient size to make a complete annular flange underneath the whole pan.

The operation of my apparatus is to min gle the gas and water first in the injector, and

then repeatedly to sub-divide and diffuse the particles of gas and Water in the receptacle A to promote the absorption of gas; and thirdly, to mingle with the current of Water which is drawn olf by the pipe 7c, the free gas which accumulates in the top of the rece tacle when there is no movement of t e water. I

Having thus set forth the nature of the invention what is claimed herein is titions, and rising through the perforations of the pans during the discharging move-- ment to be mingled the second time thereby,

and third, the rece tacle having a as-space in the top and a raft-tube exten ed from the bottom of the receptacle upward through the pans with the perforation in the gas space above the water, and the free gas entering directly from such gas-space into the draWin tube and mingling with the water in its disc arge from the receptacle Whereby the continued accumulation of gas in the said gas-space is prevented, and the gas in such space is utilized Whenever water is drawn from the receptacle.

2. An apparatus for carbonating water comprising a rece tacle for the carbonated water having at t e bottom the carbonated water-outlet j and inlet 9 for the mixed gas 1 and water, the injector connected to the said inlet and com osed of the pipe 0 with valveseat a screwed inside the same and provided with check-valve b, the pipe c having the gas-inlet a screwed upon one end and the gasnozzle 07 screwed within the opposite end, and

the T-fitting d screwed upon the outside of the same formin the Water-chamber e around the nozzle with water-inlet f at the nation, with the cylindrical receptacle A for carbonating the Water, of a series of perforated sheet-metal pans formed from square blanks a little larger than the pans, each an having four legs and each leg having its e ges sloped downwardly and terminating in I a point, and such points turned inwardly to form flat feet to support the several, pans upon one another.

In testimony whereof I have hereunto set my hand in the witnesses.
